← ScienceWhich consequence results when highly strained ionic crystal defects arise in a barium fluoride radiation detector?
A)Increased non-radioactive background noise✓
B)Enhanced electron-hole recombination rate
C)Improved energy resolution detection
D)Decreased scintillation photon wavelength
💡 Explanation
Increased background noise occurs because Frenkel defect formation induces localized non-stoichiometry, increasing conductivity via ionic transport. Therefore, spurious charges register mimicking photons rather than improving energy resolution; because they reduce output signal.
